Environment protection, electric system and ship energy efficiency

Paper

Yachts enjoy a history of development and advancement, as All it takes is a vision of what can be, belief that it can be done and the persistence and drive to make it happen. Demands for exploration are expanding. Conventional yacht design & technology will no longer be enough. Hybrid power generation, using renewable energy resources and efficiencies are the solutions to tomorrow’s...

152. Innovative Energy Systems: Motivations, Challenges and Possible Solutions in the Cruise Ship Arena

Dr ALESSANDRO BOVERI (UNIGE - DITEN)

Environment protection, electric system and ship energy efficiency

Paper

The effort on environmental issue in the maritime field has led to more stringent regulations on greenhouse gas emission (GHG). The International Maritime Organization has developed regulations intended to increase the ship’s efficiency and reduce GHG emissions in a design phase. In this perspective, several approaches and technologies adopted in land-based engineering can also be advantageous...

154. Distributed Energy Resources On-Board Cruise Ships: Integration into the Ship Design Process

Mr GIORDANO FLORE (UNIGE - DITEN)

22/06/2018, 11:45

Environment protection, electric system and ship energy efficiency

Paper

An intense innovation is characterizing energy system solutions on board ships, especially in the case of large passenger ships due to the significant total amount of installed power and the variegate typology of electrical loads. In the paper a distributed energy system will be considered for a 140.000+ GT cruise ship, in the perspective of a superior performance in terms of safety and...

137. Integrated Ship Design and CSI Modeling: a New Methodology for Comparing Onboard Electrical Distributions in the Early Stage Design

Dr Daniele Bosich (University of Trieste)

Environment protection, electric system and ship energy efficiency

Paper

In recent years, the MVDC distribution has been proposed as a viable solution for the redesign of the shipboard Integrated Power System (IPS). Indeed, there are relevant advantages promised by the innovative DC concept, among others a desirable reduction in the electric power system size. For providing a virtual proof-of-concept of this technology, parametric and interactive 3D models can be...

24. Shore-to-ship power supply integrating conventional and distributed generators along with storage

Mr Giordano Torri (Fincantieri Si spa)

22/06/2018, 12:15

Environment protection, electric system and ship energy efficiency

Paper

The need for reduction of pollution when ships are in port requires the use of a shore-to-ship power system for supplying energy to the onboard grid. The latter is normally fed at 60Hz, so a frequency conversion is needed. Power can be taken from the public power grid available on shore. In order to reduce the environmental impact, this power system can be integrated with local, distributed...

124. A mixed AC/DC low voltage electrical distribution architecture for increasing the payload on ships

Dr Giuseppe La Tona (Consiglio Nazionale delle Ricerche)

Environment protection, electric system and ship energy efficiency

Paper

This paper presents the development of a novel architecture for the low voltage electrical distribution on board using a mixed AC/DC approach. The design of the proposed solution is based on a real-world case study, i.e. the electrical distribution grid of a main vertical zone of a large cruise ship. The new electrical architecture is designed with the aim of obtaining a gradual transition...
